Master Thesis: Implement a Language Server for Code Completion




Operating and maintaining data pipelines of advanced data lakes is a challenge. Our open-source product SmartDataLakeBuilder ( makes this much more efficient by a metadata driven approach. Data objects and transformations  are configured in HOCON notation (superset of json). With this information SmartDataLakeBuilder executes the data pipelines using state-of-the-art BigData technologies (Apache Spark). In order to write the HOCON configuration files more easily, we would like to develop a service providing code completion to IDE’s by implementing the language server protocol (LSP).

Challenge: The SmartDataLake configuration file needs to be parsed and the context at a given position understood. With that it is possible to look up possible configuration options from the Scala configuration structures. Then a list of code completion hints can be created. Welcome to the world of parsers and compilers with a not so complicated entry level challenge.

In this role

The goal of the master thesis is to:

  • develop a service implementing the language server protocol with LSP4J and Java/Scala, to provide SmartDataLake HOCON notation code completion for various IDE’s.
  • Create a plugin for Visual Studio Code to use your LSP implementation
  • Bonus: Create a plugin for IntelliJ to use your LSP implementation
